CLIv2 and .NET

Are there any samples or documentation on using CLIv2 with a .NET language? Things I have already tried,

> Looking at the samples in the devkit. these are in c++ and vb5 and while I can see what they are doing, getting them to translate to a more recent version is a bit difficult. > I tried to use interop with wincli32.exe and wincli32.dll with no success. Am I trying to reference the wrong DLLs?

I am using the .NET provider already in other projects, but would like to get better performance out of some of our file exports. I really don't like shelling out or fork/exec to the external fastexport or fastload programs.
